This chapter examines the transposition of the Antitrust Damages Directive in Ireland. It first considers the transposition procedure, focusing on regulations contained in Statutory Instrument (SI) European Union (Actions for Damages for Infringements of Competition Law) Regulations 2017, before discussing the regime set out in this implementing SI. It then describes the scope of the national regime on competition law and the implementing regulations that govern full compensation, disclosure of evidence, the effect of decisions by National Competition Authorities, limitation periods, joint and several liability, the issues of ‘passing on’, the presumption and quantification of damages by cartels, and consensual dispute resolution. Finally, the chapter analyses incorrect or incomplete transposition and possible legal disputes with regard to the Directive and the implementing regulations.
